This fully-resourced lesson describes the modes of action of the T and B lymphocytes in the immune response. The detailed PowerPoint and accompanying resources have been designed to cover point 2.4 of the CIE A-level Biology specification and the structure of antibodies and the roles of memory cells is also briefly introduced.
Antigen presentation was introduced at the end of the previous lesson so the task at the start of this lesson challenges students to recognise the name of this process and then they have to spot the errors in the passage that describes the details of this event. This reminds them that contact between the APC and T lymphocytes is necessary to elicit a response which they will come to recognise as the cellular response. A series of quick quiz rounds reveals key terms in a memorable way and one that is introduced is helper T cells. Time is then taken to describe the importance of cell signalling for an effective response and students will learn how the release of chemicals by these cells activates other aspects of the response. The role of the killer T cells is also described before an exam-style question is used to check on their understanding at this point of the lesson. This leads into the section of the lesson that deals with the humoral response and students will understand how this involves the antibodies that are produced by the plasma cells that are the result of clonal selection and expansion. The remainder of the lesson focuses on the role of the antibodies and the attachment of phagocytes to opsonins.

Topics 10 & 11: Infectious disease & Immunity (CIE A-level Biology)
This lesson bundle contains 9 detailed and engaging lessons which have been designed to cover the following content in topics 10 & 11 of the CIE A-level Biology specification: 10.1: Infectious diseases * The meaning of the term disease and the difference between infectious and non-infectious diseases * The name and type of pathogen that causes cholera, malaria, TB, HIV/AIDS, smallpox and measles * Explain how cholera, malaria, TB, HIV and measles are transmitted 10.2: Antibiotics * Outline how penicillin acts on bacteria and why antibiotics do not affect viruses * Outline how bacteria become resistant to antibiotics with reference to mutation and selection * Discuss the consequences of antibiotic resistance and the steps that can be taken to reduce its impact 11.1: The immune system * State that phagocytes have their origin in bone marrow and describe their mode of action * Describe the modes of action of B and T lymphocytes * The meaning of the term immune response, with reference to antigens, self and non-self * Explain the role of memory cells in long term immunity * Autoimmune diseases as exemplified by myasthenia gravis 11.2: Antibodies and vaccination * Relate the molecular structure of antibodies to their functions * Distinguish between active and passive, natural and artificial immunity and explain how vaccination can control disease Each of the lesson PowerPoints is accompanied by worksheets which together contain a wide range of tasks that will engage and motivate the students whilst challenging them on their understanding of the current topic as well as previously-covered topics.

Topic 11.1: The immune system (CIE A-level Biology)
The 4 lessons contained within this bundle are detailed and will engage the students whilst covering the following content in topic 11.1 of the CIE A-level Biology specification: * State that phagocytes have their origin in bone marrow and describe their mode of action * Describe the modes of action of B-lymphocytes and T-lymphocytes * Explain the meaning of the term immune response, making reference to the terms antigen, self and non-self * Explain the role of memory cells in long-term immunity * Explain, with reference to myasthenia gravis, that the immune system sometimes fails to distinguish between self and non-self The PowerPoints and accompanying resources contain a wide range of tasks, which include exam-style questions, guided discussion periods and quiz competitions, and these have been designed to check on the students' understanding of the current topic as well as previously-covered topics
